Oct 04, 2018 Also, the magnetic force in a separator can be maximized by matching the magnetic field gradient to the particle size. Magnetic separator separates the iron ore feed material into two or more components. If the purpose is to produce a magnetic concentrated iron ore then the other component which is non-magnetic is the tailings.

magnetic separation. Dry Magnetic Separation of Iron Ore: There are many inherent advantages in processes that utilize dry magnetic separation to beneficiate iron ore. Wet concentration of magnetite ore, in comparison, re- quires 500 to 1000 gal of water per ton of concen- trate produced. This means extensive use of water

Jan 01, 2015 Based on the magnetic susceptibility values in Table 9.1, iron ore can be divided into two groups, namely, strongly magnetic iron ores, that is, magnetite (72.4% Fe), and weakly magnetic iron ores (oxidized iron ores), that is, martite (70.0% Fe), hematite (70.0% Fe), specularite (70.0% Fe), limonite (57.14–59.89% Fe), and siderite (48.2% Fe ...
